Abstract

An artificial lash extension system includes lash extensions designed for an application under a natural lash. Each of the lash extensions includes clusters of artificial hairs. Each of the clusters includes at least two artificial hairs and a base from which the at least two artificial hairs of each of the clusters protrude. Each of the lash extensions is formed by at least an application of heat at a respective base.

Claims

exact text as granted — not AI-modified

       6. The artificial lash extension system of  claim 5 , wherein the base is formed by at least the application of heat. 
     
     
       7. The artificial lash extension system of  claim 6 , wherein the plurality of clusters are connected together by at least the application of heat. 
     
     
       8. The artificial lash extension system of  claim 1 , wherein the plurality of lash extensions are designed for an application under the natural lashes in an arrangement adjacent to one another under the natural lashes. 
     
     
       9. The artificial lash extension system of  claim 1 , wherein one or more of the at least two artificial hairs of a first cluster of the plurality of clusters crisscross one or more of the at least two artificial hairs of a second cluster of the plurality of clusters. 
     
     
       10. The artificial lash extension system of  claim 1 , wherein an artificial hair of a first cluster of the plurality of clusters crisscrosses another artificial hair of the first cluster. 
     
     
       11. The artificial lash extension system of  claim 1 , wherein the application of heat facilitates at least a partial melting of one or more of the plurality of clusters. 
     
     
       12. The artificial lash extension system of  claim 1 , wherein the application of heat comprises heat sealing. 
     
     
       13. The artificial lash extension system of  claim 1 , wherein the application of heat comprises heat fusing. 
     
     
       14. The artificial lash extension system of  claim 1 , wherein each of the plurality of lash extensions is further formed by an application of an adhesive. 
     
     
       15. The artificial lash extension system of  claim 14 , wherein the plurality of clusters are connected together by at least the application of the adhesive. 
     
     
       16. The artificial lash extension system of  claim 1 , wherein the plurality of lash extensions are designed for an application under the natural lashes proximate to a lash line. 
     
     
       17. The artificial lash extension system of  claim 1 , wherein a thickness of the base ranges between 0.05 millimeters (mm) and 0.15 mm inclusive. 
     
     
       18. The artificial lash extension system of  claim 1 , wherein a thickness of the base is less than 0.3 millimeters. 
     
     
       19. An artificial lash extension system, comprising:
 a container; and 
 a plurality of lash extensions releasably coupled to the container, each of the plurality of lash extensions comprising:
 a plurality of clusters of artificial hairs, each of the plurality of clusters comprising at least two artificial hairs; and 
 a base, wherein the plurality of clusters are attached to the base by at least an application of heat, wherein the at least two artificial hairs of each of the plurality of clusters protrude from the base, wherein at least some of the artificial hairs of at least one of the plurality of clusters are coupled to one another at a respective part of the base, and wherein the base is designed to at least attach to an underside of natural lashes. 
 
 
     
     
       20. The artificial lash extension system of  claim 19 , wherein the at least two artificial hairs comprise a synthetic material. 
     
     
       21. The artificial lash extension system of  claim 20 , wherein the at least two artificial hairs comprise polybutylene terephthalate (PBT). 
     
     
       22. The artificial lash extension system of  claim 20 , wherein the at least two artificial hairs comprise polyester.
